The new genus is more or less related to Gastrodia, Aphyttorchis, Epi- 

 pogon and Golem, in its leafless habit. It is, however, closely aUied to 

 Cheirostylis in the gamophyllous perianth, deeply sinuate rostellum, sectile 

 pollinia, one or two armed columnal appendages and stigmatic tissue at the 

 base on each side of the rostellum. But it differs from it by the aphyllous 

 habit, and by the nearly included long entire labellum with no distinction 

 of a blade and claw and with no swelling at the base.
